Why prices move

Supply, demand and expectations

Members

In this lesson

See how news, supply, demand and especially expectations move prices — and why good news can make a price fall.

Key takeaways

Prices move when the balance of supply and demand changes.
Expectations matter most: markets often move before the news, not after it.
'Priced in' means the market already expects it — so the news itself changes little.
Surprises, good or bad, cause the biggest moves.
